[n.d. c.1780.]
A very rare copper engraving. 140 x 95mm. 5½ x 3¾". Trimmed to the plate and laid on separate sheet.
Regnier de Graaf (1641-1673) was a Dutch physician and anatomist who made key discoveries in reproductive biology. As a Catholic in a protestant country he was unable to follow a university career, so he studied medicine at Utrecht and Leiden, and went onto Angiers where he submitted his doctoral thesis on the pancreas. He then turned to the study of the male genitalia, which led to a publication in 1668. De Graaf's position in the history of reproduction is unique. He made many advances with his personal contributions including the description of testicular tubules, the efferent ducts, corpora lutea and the description of the function of the Fallopian tubes and hydrosalpinx. De Graaf's main discoveries include his research detailing the development of the ovarian follicles and how they contained the oocyte; and his description of the female ejaculation and his references to the erogenous zone in the vagina, which he himself linked with the male prostate.
